I Application filed October 8, 1915. Scrial No. 54,749.

- To all whom it may concern):

Be it known that I, WILLIAM R. PORTER,

a citizen of the'United States, and a resident of Agricultural College, in the county of Cass and State of North Dakota, have in-' vented an Improvement .in Seeding-Ma- An object of the invention is the proviv slon of a novel means for forming a furrow i of uniform depth regardless of the unevenness of the surface or density of the soil itself whereby seed deposited therein, will germinate evenly and thus produce a uni form crop.

Another ob ect is to provide means for ad usting certain parts so as to regulate the depth of the furrow which should vary according to'the, kind of seed being planted.

The inventive idea involved is capable of receiving a varietywf mechanicalexpressions, some of which, for the purpose of illustrating the invention, are shown in the accompanying drawing, in whiel Figure 1 is a fragmentary side elevation of a seeding machine showing the invention applied thereto. Fig. 2 is a section on the line 22 of Fig. L Fig. 3 is a. section on the line Fig. 1. Fig. 4 is a side clevation of amodified form of the invention.

.Fig. 5 is a section on the line 5 of Fig, 1.

Referring to the drawings and more particularly to Figs. 1 to 21 inclusive, the nu: ineral 10 indicates generally .a portion of the main frame of a. seeding machine of ordinary construction having mounted therein a large covering wheel 11 which is adapted to cover the furrow after the seeds have been planted, as shown in Fig. 1. Forwardly of the wheel ll the frame has mount ed thereon the usual seed hopper 1'2 having a feed 1? in the bottom thereof which is mounted in the vertical tube portion H of the ordinary Form of furrow shoe 1.: which is usually employed on machines of this character. l'referahly formed integrally with the vertical portion ii and arranged on each side tlicroofaud oll sct thercl roui is a downwardly extruding supporting arm ll? to which is secured, by means of a. lad, 27, the adiaeeut end of an arm forming a portube or chute23.

tion of the pivoted frame 1-8, the other ends 1 of the arms converging forwardly and being secured to the forward end of the shoe 15. Each arm of the -.frame 18 has extending therefrom at its rcargend a stub axle 19 on which is mounted a wheel 20 which is adapted to engage the ground on .each side of the furrow substantially opposite the deepest point thereof whereby the depthof the same is uniformly maintained. Should it be desired to increase .or decrease the depth of the furrow it is only necessary to unloosen the bolt 17 and move the inner end of the frame 18 upwardly or downwardly on the arm 16. The dotted line position in Fig; 1 shows an adjustment of .the shoe 15 when it is desired to increase the depth of the fur row. 1

In the embodiment in Figs. 4 and 5, a single concave-convex disk 21 is employed in lieu of the shoe l5 and is 'journ aled in the curved forwardly extending arm 22the upper end oi'twhich is connected to the vertical seed- The lower end of said arm preferably has extending therefrom in a diagonally upward direction the draw bar 24 havin" mounted thereon at right engle sa rod 20 the upper endof which is secured to a portion of the frame of the machine. This rod 25 has coiled thereabout a spring '36 which is adapted to exert a pressure upon said draw bar whereby a fairly constant pressure is indirectly maintained upon'the disk 21. The a no 22 has preferably formed integrally therewitl i anoffset therefrom curved support 2? similar t the support 16,

in Fi e. 1 and is adapted to have connected I thereto, by means of a set screwQB, the rear end of a swinging member 29 the forward end of which is secured to the draw bar. 24.- as indicated at 30.

The member '29 adjacent its im cr end is provided with a stub axle ill upon which is mounted the wheel 2-32. It will thus he seen that, in this con strurtion also, the wheel is arranged alongside of the furrow opener in such manner that the point of contact of the Wheel. with the surface oi? tnc ground will. be substautizdly opposite the lowest point of the fin-raw opener. When. it is found necessary to rhangc the depth of the furrow the set arrow 2-8 is loosened and the member 29 swung upwardly or downwardly along the support ii until the relative position he turcu the dish ll and wheel 15:? is such that the desired depth of the furrow is secured- It will be observed from the foregoing description taken in connection with the drawing that the surface engaging wheels are, in each instance, arranged alongside of the furrow opener so that the point of contact of the wheels with the surface of the ground is substantially opposite the lowest point of said furrow opener. This construction is primarily designed to permit of the furrow opener making a furrow of uniform depth and is in contradistinction to known con- 1 structions, wherein the supporting wheels are arranged rear wardly of the furrow shoes, which fact prohibits the possibility of opening a furrow of uniform depth when the machine is traveling over uneven surfaces.

What is claimed is A seeding machine comprising a furrow forming implement having a substantially vertical tubular portion, a support extending longitudinally of said vertical portion on each side thereof, a frame pivoted at its forward end to said implement and having a member extending rearwardly on the outer side of each support and terminating adjacent thereto, a bolt extending transversely of said members and connecting the rear ends thereof whereby the same may be drawn together to bind and secure them to said supports to permit of vertical adjustment of said furrow forming implement, and ground engaging elements for supporting said frame and having their axes of rotation through said supports.
